AM79C874VC – AMD

The AM79C874VC is an AMD single-chip Ethernet controller fabricated using a CMOS process, indicated by the ‘C’ in the part number. This device implements the IEEE 802.3 CSMA/CD protocol and supports 10BASE-T Ethernet networks. The ‘D/C 0623’ marking signifies a date code of week 23 of 2006. Functionally, the AM79C874VC integrates media access control (MAC) and physical layer (PHY) functions, providing a direct interface to the network medium via a twisted-pair cable. It features internal transmit and receive FIFOs to buffer data, reducing CPU overhead during network operations. The ‘NON-RoHS’ designation indicates that this specific production run does not comply with the Restriction of Hazardous Substances Directive, potentially containing lead or other restricted materials in its construction.
